## Million billion trillion quadrillion

The regular numbers that we know and use a lot daily and are also used by economists in the financial world, but have you asked what kind of numbers are used by astronomers and naturalists or atom scientists, how are counted under the microscope and cells and the number of stars in galaxies It is very many and our regular numbers used certainly do not count them.

## What is a million?

A million is a thousand and one and six zeros are written

The pronouncement of a million Italian origins from the Latin word (mille), which means in Latin, Italian and French, a thousand with the position of (ion) to amplify the meaning of a large or huge thousand. It appeared in Italy in the late thirteenth century and then moved to France in the late fourteenth century and then to England In the sixteenth century, from England, it moved to most of the world.

## What is a billion?

A billion is a thousand million, and one and nine zeros are written, but it is more common to use the word billion, and the word billion is derived from the French word (milliard).

## What is a trillion?

This number has two systems, the English and the American, and each of them has a definition of a trillion

In the American system: this number means one thousand billion, or equal to one million – million, and is written one and twelve zeros.

In the English system: this number means a million raised by the three parentheses, so the word begins with the word (tri), and he writes one and eighteen zeros.

It is interesting to mention that if people in the world stood on a scale, the weight of humans would be about a trillion pounds. The number of seconds in a hundred thousand years is approximately three trillion seconds, and the number of kilometres travelled by light during a light year is six trillion kilometres, and we need four trillion millimetres of tape to tie a knot around the sun.

## What is a quadrillion?

This number also has two systems, the English system, and they use what is called the long scale or the long table, so the number is one million- million -million- million, and one and twenty-four zeroes are written.

Or the American system, and they use what is called the short scale or the short scale, so the number is one thousand million- million, and writes one fifteen zeros.

It is interesting to mention that there are about a quadrillion ants on the globe, and about a tenth of that number of bacteria on your body.

## What is Short scale and long scale for numbers?

They are two systems naming large numbers used all over the world to represent the correct decimal.

Most continental Europe use the long scale, but most English-speaking countries use the short scale, and in each country the numbers are translated into the local language of the country, but sometimes they are similar due to the common origin of the name and in some countries such as East Asia they have systems for naming large numbers that differ from the long and short system.

The long scale refers to a system of names of large numbers in which each new term is greater than a million times the previous term, for example a billion means a million-million, a trillion means a million billion, and so on.

The short scale: It refers to a system for the names of large numbers in which each new term is a thousand times greater than the previous term, for example a billion means a thousand million, a trillion means a thousand billion and so on

The number one thousand million (billion) is excluded from this scale, as it is successive in the two systems and writes 1 and nine zeros in the two systems.

But in the other big numbers the two systems diverge greatly.

In the nineteenth and twentieth centuries, Britain used the long scale, while America used the short scale, and in 1974 Britain switched to the short scale, but these two systems were no longer accurate.
